Pss knockdown in the midgut causes growth retardation in Drosophila similar to that in human LMHD
Developmental Dynamics, EarlyView.Abstract Background Phosphatidylserine synthase (PSS), localized in the mitochondrial membrane, synthesizes phosphatidylserine. In humans, mutations in Pss lead to Lenz–Majewski hyperostotic dwarfism, a disorder affecting growth and development. The effects of Pss mutations on the growth of Drosophila melanogaster are not fully known. Hence, this study

Maxillary sinus antrostomy Pitfalls [PDF]
, 2012 Endoscopic sinus surgery which is the commonly performed nasal surgery has its own problems ifnot performed properly. Success of maxillay sinus antrostomy depends on including the naturalostium to the antrostomy.

Acute dacryocystitis: two cases reports [PDF]
, 2011 The adult lacrimal obstruction can be congenital or acquired. In the case of the acquired form, the etiology classifies in not-specific (it involves the coating epithelium and/or the vascular plexus submucosae of the lacrimal duct) and specific ...

Endoscopic Transnasal Apicoectomy for Odontogenic Maxillary Sinusitis
The Laryngoscope, EarlyView.Endoscopic transnasal apicoectomy (ETA) is a novel multidisciplinary technique that combines endoscopic sinus surgery with apicoectomy via a transnasal approach. ETA enables direct access to periapical lesions while preserving the causative tooth. Our initial experience suggests that this minimally invasive approach is safe, feasible, and effective for

Evaluation and Treatment of Congenital Nasolacrimal Duct Obstruction
Beyoglu Eye Journal, 2018 Congenital nasolacrimal duct obstruction is a common problem in neonates that results in epiphora, superimposed infection and amblyopia. Our aim is to review causes and current management of this problem in pediatric population.

Nasolacrimal duct opacity on CT
The British Journal of Radiology, 1996 Abstract A retrospective analysis of 100 coronal sinus CT scans was performed to investigate the frequency of opacity of the nasolacrimal duct and determine if there was any correlation between the pattern of duct opacity and the presence of inflammatory sinus disease.

Inter‐Crystal Spacing of Implantable Polymeric Surfaces as a Key Suppressor of Microbial Adhesion.
Small, EarlyView.Biofilm formation on implantable devices is addressed by controlling inter‐crystal spacing in shape memory polymers. Repeated shape recovery aligns and enlarges crystalline phases and reduces amorphous regions, enhancing bacterial repellency. Three biofilm‐forming bacteria show reduced adhesion, and a one‐year dog bile‐duct model maintains function ...

A rare cause of nasolacrimal duct obstruction: Dentigerous cyst in the maxillary sinus
Indian Journal of Ophthalmology, 2009 The most common abnormality of the lacrimal drainage system is congenital or acquired nasolacrimal duct obstruction. The causes of acquired nasolacrimal duct obstruction may be primary or secondary.

Endonasal versus external dacryocystorhinostomy for nasolacrimal duct obstruction [PDF]
, 2017 BACKGROUND: A dacryocystorhinostomy (DCR) procedure aims to restore drainage of tears by bypassing a blockage in the nasolacrimal duct, through the creation of a bony ostium that allows communication between the lacrimal sac and the nasal cavity.
